A and refrigerating purposes, there being a pas- Heretofore devices of this character have sage way 9 in thesame leading to the boiler, been constructed, but owing to the multiand a passage way 10 in which is secured a plicity of parts employed, entail great expipe 11 leading to the cooling or storage tank,

there also being a passage way leading from the cock to a pipe 12 leading into the boiler to near the bottom of the same where it is coiled and perforated, and in the apparatus for freezing or refrigerating, there is a passage way 13 communicating with pipe 14 which returns the gases from the freezing and refrigerating coils back into the boiler.

15 designates the coolingchambersurrounding the annular concentric receptacle or storage tank 16 for the cooling medium, closed at both ends and water tight, this receptacle being slightly raised from the bottom of the cooling chamber to allow a free circulation of water around the receptacle, the cooling chamher being insulated from atmospheric contact by a covering 17 inclosing the same.

In the use of the apparatus as a refrigerator or for freezing and refrigerating, as the cooling medium is led from the storage tank to the place of use, for refrigerating, or for refrigeratin g and freezing, the cover is omitted.

18 designates a pipe in communication with a water supply and extending into the boiler, a lower portion being coiled as at 19, turned at right angles at the bottom, and extending through the boiler and drum and is connected with an overflow pipe 20 tapped into the cool-' ing chamber 15.

At 21 there is a union upon pipe 18 into which a pipe 22 is secured which enters the receptacle 15, a cook 23 in the union controlling the admission of water into the boiler or cooling receptacle.

24 designates a vent plug screwed into the top of receptacle 16.

20 designates a draw off pipe connecting overflow pipe 20 and cooling chamber 15, which is supplied with a valve 20 by which to draw off the water in the cooling chamber. In the use of the apparatus for refrigeration, or freezing ice and refrigeration, the drawoff cock 20" is dispensed with.

241' designates a pipe leading from the storage tank 16, to a coil 24: which is designed to be either placed in a room to be cooled, or in a refrigerator 25 to cool the same, or in a refrigerator to both manufacture ice and cool the same.

In Fig. 4 I have illustrated a preferred form of refrigerator, which has an outer andinner wall 26 and 27 respectively, leaving an air space 28 in which the air in the refrigerator circulates, there being an ice box 29 and a water box 30. Coil 24" in this construction is formed with a freezing coil 24" in the ice box 27 and a coil 24"" in the refrigerator, preferably near the top, as the warm air after being cooled falls, and warmer air from below rises keeping a circulation of the air, so as to keep the same in contact with the freezing coil, thereby keeping an even cool temperature in the refrigerator.

In operation, when using the apparatus for the manufacture of ice, a quantity of aqua ammonia isintroduced into the boiler through an opening in the head closed by screw plug 7, a fireis built in the drum 3 and the aqua ammonia heated to a degree to release the ammoniacal gas, the stem of the three way cock is turned to allow the gas to find exit through way 9 and into pipe 11 and nto the storage tank 16, screw plug 24* therein is removed to give the air vent, until it is all removed when the plug is screwed to place. At the same time the fire is started under the boiler, cock 23 is turned so that the water flows through pipe 22 into the cooling chamber 15, which cools the hot gas received in the storage receptacle 16 as it comesfrom the boiler and in connection with the pressure liquefies the gas. The water after being heated by contact with the hot gas conduits flows off through overflow pipe 20. When all the gases are driven off from the aqua ammonia, therefore leaving only water 1n the boiler, the fire is extinguished, cook 23 urned to cause the water to flow through pipe 18 and coil 19 thus cooling the boiler and thereby lessening the pressure in the same. Cock 20" is now opened and the water in the coollng chamber is all drawn off, and an annular pan is filled with water and inserted around the storage tank 16 and a circular can is inserted in the space embraced by the storage tank. The stem of the three way cock is now turned so that the pipes 11 and 12 are in communication, and the liquid ammonia now begins to evaporate, the pressure in the boiler being removed as described, and flows through pipes 11 and 12 and through the perforations 1n the bottom of pipe 12, where it is absorbed by the water remaining in the boiler and produces the original aqua ammonia. As the process of evaporation takes place or as the liquid is changed to a gas it becomes intensely cold and absorbs heat from everything thus freezing the water in the cans and forming ice, the cans are now removed, the ice taken therefrom, and the apparatus is ready for another like operation.

If the apparatus is used for refrigerating or cooling purposes, the operation is the same as just described only a return pipel t being used from the refrigerating coil, instead of the pipe 11 which necessitates another passage way for the cock making it a four way cock, there being an expansion valve 14 by which to control the temperature of the coil, and if the apparatus is used for refrigeration and freezing ice it is the same as for refrigeration. In this instance the freezing coil being in water will freeze the Water making ice and the refrigerating coil will cool the atmosphere in contact therewith.

It will be apparent that I can have several coils in diiferent places, for cooling, or freezing ice, and that I do not limit myself to any form of refrigerator or cooling chamber.

In places where steam is used it is obvious that the gas may be generated by steam and in this instance I connect pipe 18 with the steam pipe as Well as the water pipe, and dispense with drum 3,

518,791 p is It will be seen that the apparatus is adaptable to a construction that is portable, and convenient for family use, or capable of a construction for fixed use in a mercantile business, or for manufacturing ice for the trade, the greatest claim herein being to economy of construction, ease of management and adaptability to all uses.
